This application is a continuation of U.S. application Ser. No.16/705,389, filed Dec. 6, 2019, which is a continuation of U.S.application Ser. No. 15/702,252, filed Sep. 12, 2017, now U.S. Pat. No.10,502,419, each of which is incorporated in its entirety herein byreference.

TECHNICAL FIELD

The present invention generally technically relates to portablebiometric lighter devices, and more specifically, to portable lightersusing biometric data to prevent unauthorized usage. The presentinvention technically relates to devices ensuring that a user of aportable lighter is an authorized user and that a minor will not be ableto activate the portable lighter.

BACKGROUND ART

Portable lighters are commonly used for lighting cigarettes, tobaccopipes, cigars, charcoal grills, pilots of gas appliances, fireplaces,water-heaters, and campfires. These portable lighters are typicallyactivated by a user opening a cap, manually flicking a wheel to create aspark, and depressing a button that allows lighter fluid to flow.Unfortunately, these typical portable lighters have no safety mechanismto prevent an unauthorized user, such as a child, from activating aflame and accidently causing fire and bodily injuries, or otherunauthorized users from intentionally causing fires. While some portablelighters have incorporated safety precaution mechanisms to deal with thepossibility of misuse of a portable lighter, such examples include aportable lighter that incorporates a gas valve button that will notallow lighter fluid to flow unless a force of an adult finger is appliedto the gas valve button, and a portable lighter that incorporates anelectronic alphanumeric keypad to control access to the portablelighter's ignition mechanisms. These examples, however, have theirshortcomings in that they are not user-friendly for the authorized userand the safety mechanisms that are in place can easily be tampered by achild.

With respect to the portable lighter that incorporates a gas valvebutton, requiring the force of an adult's finger, an authorized adultuser may not always be able to apply the force necessary to activate thebutton or an older aged child may have the ability to apply a force thatmimics that of an adult. With respect to the alphanumeric keypad andrequiring a security code to activate the lighter, an authorized usermay forget the security code or a child can gain access to the code bymerely viewing the authorized user enter the security code.

Thus, a long-felt need exists in the art for a portable lighter that isable to easily recognize the authorized user of the portable lighter andthat is able to prevent an unauthorized user, e.g., a child, frommimicking the authorized user. The incorporation of a biometric sensorand biometric data, such as a fingerprint sensor and a fingerprint data,satisfies the aforementioned needs.

Referring to FIG. 2, a partial exploded view of the portable biometriclighter device 100 is shown, in accordance with the embodiment of FIG.1, the device 100 comprising a label 160, a body cover 130, a biometricsensor, e.g., a fingerprint sensor 140, an LED 150, a control unit 210,a plurality of power lines 220 a and control lines 220 b, a plurality ofLED apertures 230, and a plurality of fingerprint sensor apertures 240.

Referring to FIG. 3, a cross-sectional view of the portable biometriclighter device 100 is illustrated, in accordance with the embodiment ofFIG. 1. The device 100 comprises a cap 110, a body 120, a biometricsensor, e.g., a fingerprint sensor 140, an LED 150, a control unit 210,a plurality of power lines 220 a, a plurality of control lines 220 b, aset switch 170, a gas lever 350, an active switch 320, a lighter fluidvalve 310, a nozzle 340, a pulse igniter 370, a pole 330, a lighterfluid 360, and a power source 380. Alternatively, an electric gas valve(not shown) may be used in place of the cap 110.

A power source 380 is operably coupled to a control unit 210 and ishoused within a body 120. The power source 380 can be a primary cellbattery, a rechargeable battery, or a photo-voltaic cell, by exampleonly. The power source 380 provides power to the control unit 210 and/orthe fingerprint sensor 140 via a plurality of power lines 220 a.

The active switch 320 is operably coupled to the fingerprint sensor 140such that upon a user flipping open the cap 110, the gas lever 350 ispulled up and activates the active switch 320 via contact force orelectromagnetic force. The active switch 320 upon activation thenactivates the fingerprint sensor 140 to read or scan a fingerprint. Thegas lever 350 is also configured to lift the nozzle 340, which allowsthe lighter fluid 360 to be released from the lighter fluid valve 310,upon the user flipping open the cap 110.

A pulse igniter 370, such as a piezoelectric based circuit, isconfigured to produce a high voltage spark from a pole 330 to the nozzle340 upon the control unit 210 determining a match between a scanneduser's biometric data, such as the user's fingerprint and the authorizeduser's biometric data, e.g., authorized user's fingerprint, that ispreviously stored in a memory device (not shown). A flame issubsequently produced when the high voltage sparks come in contact withthe lighter fluid 360 that is flowing through the lighter fluid valve310 to the nozzle 340.

Referring to FIG. 4, a flowchart illustrates the steps of a method M₁ ofsetting-up/teaching an authorized user's biometric data, e.g.,fingerprint, to the portable biometric lighter device 100, by way of abiometric lighter device 100, in accordance with the embodiment ofFIG. 1. The first teaching step 410 comprises the step of an authorizeduser depressing a set switch 170. The second teaching step 420 comprisescommencing periodic or repetitious blinking by an LED 150 to indicatethat the fingerprint sensor 140 is ready to scan. The third teachingstep 430 comprises the step of an authorized user swiping or depressinghis or her finger, preferably the thumb or the index finger, over thefingerprint sensor 140. If an error in scanning the fingerprint occurs,the LED 150 continues to blink repeatedly as indicated by method stepblock 435. The fourth teaching step 440 comprises the fingerprint sensor140 successfully scanning and storing fingerprint data in a memorydevice, wherein the LED 150 remains lit for a brief interval beforeextinguishing. According to block 450, this process of teaching may berepeated until a manufacturer pre-determined maximum number offingerprints is stored, e.g., 4 fingerprints. In this embodiment, thestored fingerprints are not erasable or changeable.

Referring to FIG. 5, a flowchart shows the steps of an alternativemethod M₂ of teaching an authorized user's fingerprint to the portablebiometric lighter device 100, in accordance with the embodiment of FIG.1, wherein prior fingerprint that being stored in a memory device iserased upon teaching of a new authorized user's fingerprint.

The first alternative teaching step 510 in the method M₂ involves anauthorized user depressing/activating a set switch 170. Then the secondalternative teaching step 520 comprises deleting prior storedfingerprint data of an authorized user from a memory device (not shown).The third alternative teaching step 530 comprises commencing periodic orrepetitious blinking by an LED 150 to indicate that the fingerprintsensor 140 is ready to scan in new authorized user's biometric data,e.g., a fingerprint. The fourth alternative teaching step 540 comprisesswiping by an authorized user's finger, preferably the thumb or theindex finger, over the fingerprint sensor 140. If an error occurs inscanning the fingerprint, the LED 150 continues to blink repeatedly asindicated by method step 545. The fifth alternative teaching step 550comprises successfully scanning and storing a fingerprint scan in amemory device (not shown) by the fingerprint sensor 140, wherein the LED150 remains lit for a brief interval before extinguishing.

Referring to FIG. 6, a flowchart illustrates the steps of activating,e.g., igniting a flame, by the portable biometric lighter device 100, inaccordance with the embodiment of FIG. 1. The first step of igniting aflame 610 comprises a user opening a cap 110, whereby a gas lever 350 isactuated, thereby actuating an active switch 320 via contact pressure orelectromagnetic force. The actuation of the gas lever 350 alsosimultaneously causes a lifting of a nozzle 340, which allows thelighter fluid 360 to be released from the lighter fluid valve 310.

The second step 620 of igniting a flame comprises the active switch 320,activating, via a control unit 210, the fingerprint sensor 140 to reador to scan a fingerprint and to repeatedly blink an LED 150 indicatingto the user that the fingerprint sensor 140 is in “scan” or “read” mode.The third step 630 of igniting the flame comprises the control unit 210determining that the scanned fingerprint matches an authorized user'sfingerprint that is stored in memory. If the scanned fingerprint matchesan authorized user's fingerprint that is stored in memory, the controlunit 210 will activate a pulse igniter 370, e.g., a piezoelectric basedcircuit, thereby generating a plurality of high voltage sparks throughthe pole 330 to the nozzle 340. A flame is thereby generated via lighterfluid 360 flowing through the nozzle 340. However, if the scannedfingerprint does not match an authorized user's fingerprint that isstored in memory, the LED 150 will blink in a red color and thensubsequently in a green color as the fingerprint sensor 140 continues toread or scan a fingerprint.

While the embodiment in FIG. 6 involves the control unit 210 activatinga pulse igniter 370 upon a fingerprint match, alternative embodimentsmay also involve the control unit 210 deactivating, via a solenoid andat least one of the following elements: a push button (not shown), a caplock (not shown), the cap lock being releasable, a gas valve lock (notshown), an electric gas valve (not shown), the electric gas valve beingswitchable to an “on” position. The fourth step 640 of igniting a flamecomprises the user closing the cap 110, thereby extinguishing the flameand the control unit 210 deactivating the fingerprint sensor, e.g.,sleep mode.

Referring to FIG. 7, a circuit diagram of the portable biometric lighterdevice 100 is shown, in accordance with the embodiment of FIG. 1. Theportable biometric lighter device 100 comprises a control unit 210, apower source 380, a control line 220 b, a set switch 170, an exemplarypulse igniter circuit 710, and an active switch 320. The power source380 continuously provides power to the control unit 210.

Referring to FIG. 8, an alternative circuit diagram of the portablebiometric lighter device 100 is illustrated, in accordance with theembodiment of FIG. 1. In particular, device 100 is shown having controlunit 210 coupled to fingerprint sensor 140. In the depicted embodiment,control unit 210 may be implemented using a microcontroller such as theARM thumb-based microcontroller Model No. AT91SAM7S256, available fromARM, Inc., of Austin Tex. In addition, the fingerprint sensor 140 isshown implemented using the ATW210 fingerprint sensor available fromAtrua Technologies, Inc., of Campbell Calif. FIG. 8 also shows USB port810 coupled to leads 56 and 57 of control unit 210.

Power source 380 is shown providing power to voltage regulator 805. Thevoltage regulator is shown implemented using the TPS76933 voltageregulator provided by Texas Instruments of Dallas, Tex. It is understoodthat during operation of voltage regulator 805, a reference voltage of1.7V or greater on input 3 will disable the internal circuitry of thevoltage regulator, thus significantly reducing the supply current viaoutput 5. On the other hand, a voltage of less than 0.9 V on input 3will enable the voltage regulator and will enable operation of thecontrolled devices (e.g., control unit 210 and fingerprint sensor 140).Accordingly, in the embodiment of FIG. 8, the power source 380 does notprovide power to the control unit 210 and the fingerprint sensor 140until a user flips open the cap 110 that activates the gas lever 350 andthe active switch 320 or the user depresses the set switch 170.

Control unit 210 is shown with leads 1-33 along the left side of thecontrol unit, and leads 34-64 continuing along the opposing side. Table1 setout below includes a pinout of the leads implemented by controlunit 210.

With reference to FIGS. 10 and 13,in some embodiments, the body 1020 is configured to include one or moreof the following elements: a fingerprint sensor 1040, an LED 1050, acontrol unit 1010, power lines 1025, control lines 1035, a set switch1070, a gas lever (akin to the one shown in FIG. 3), an active switch1015, a lighter fluid valve (akin to the one shown in FIG. 3), a nozzle(akin to the one shown in FIG. 3), a pulse igniter 1075, a pole (akin tothe one shown in FIG. 3), a lighter fluid reservoir (akin to the oneshown in FIG. 3), a power source 1080, and a memory 1090. As can be seenin FIG. 12, the body 1020 of the exemplary portable biometric lighter1000 includes an aperture 1022 for providing access to the set switch1070, an aperture 1026 for connecting a USB-based charger, and aturn-knob 1028 for adjusting the size of the flame emitted by theportable biometric lighter 1000.

In the exemplary embodiment illustrated in FIG. 13, the biometric (i.e.,fingerprint) sensor 1040 of the portable biometric lighter 1000 isoperably coupled to a control unit 1010. The biometric sensor 1040 ishoused at least partially within the body 1520 but includes anexterior-facing fingerprint reading surface located at a top surface ofthe push-button 1030 that is accessible by a user and that is configuredto scan an authorized user's biometric data (e.g., fingerprint) and anyother user's biometric data (e.g., fingerprint), which may be stored inthe memory 1090 of the portable biometric lighter 1000.

The LED 1050 of the portable biometric lighter 1000 is operably coupledto the control unit 1010 and is configured to provide indications to auser, via blinking and/or solid color or colors, the status of theportable biometric lighter functions including but not limited tosetup/teaching mode, low battery, failed scan, and incorrect match. Forexample, in some embodiments, when the portable biometric lighter 1000is ready to read a user's fingerprint, the LED 1050 is illuminated in ablue color, when the user's scanned fingerprint matches an authorizeduser fingerprint stored in the memory 1090, the LED 1050 is illuminatedin a green color, and when the user's scanned fingerprint does not matchan authorized user fingerprint stored in the memory 1090, the LED 1050is illuminated in a red color.

The set switch 1070 of the portable biometric lighter 1000 is operablyconnected to the control unit 1010 and is housed in the body 1020. Inthe embodiment illustrated in FIGS. 10 and 13, the set switch 1070 isaccessible through an aperture 1022 of the body 1020. In someembodiments, the set switch 1070 is configured to activate the controlunit 1010 for accepting a new fingerprint, and to optionally erase aprior fingerprint from the memory device 1090 of the portable biometriclighter 1000 if the control unit 1510 is configured to allow erasing aprior fingerprint and accepting a new fingerprint.

With reference to FIG. 13, a power source 1080 is operably coupled tothe control unit 1010 and is housed within the body 1020. In someembodiments, the power source 1080 is a primary cell battery, arechargeable battery, a photo-voltaic cell, or the like. In theembodiment illustrated in FIG. 13, the power source 1080 provides powerto the control unit 1010 and/or the fingerprint sensor 1040 via thepower lines 1025, but in some approaches, the power source 1080 may beoperatively coupled to the control unit 1010 and/or to the fingerprintsensor 1040 via suitable alternative means.

In the embodiment illustrated in FIGS. 10-13, the active switch 1015 isoperably coupled to the fingerprint sensor 1040 such that upon a userpressing down on the push-button 1030, the gas lever of the portablebiometric lighter 1000 is actuated and activates the active switch 1015via contact force or electromagnetic force. The active switch 1015 uponactivation then activates the fingerprint sensor 1040 to read or scan afingerprint. In some embodiments, upon the user depressing thepush-button 1030, the gas lever of the portable biometric lighter 1000is also configured to lift a nozzle of the portable biometric lighter1000, which allows the lighter fluid to be released from the lighterfluid valve.

A pulse igniter 1070, such as a piezoelectric based circuit, isconfigured to produce a high voltage spark from a pole of the portablebiometric lighter 1000 to the nozzle of the portable biometric lighter1000 upon the control unit 1010 determining a match between the scannedbiometric data (e.g., fingerprint) of a user and the biometric data(e.g., fingerprint) of an authorized user, which is stored in the memory1090 of the portable biometric lighter 1000. A flame is subsequentlyproduced when the high voltage sparks come in contact with the lighterfluid that is flowing through the lighter fluid valve to the nozzle.

Referring to FIG. 14, a flowchart illustrates the steps of a method 1400of activating, e.g., igniting a flame, by the portable biometric lighter1000 depicted in FIGS. 10-13. The first step 1410 of the method 1400 ofigniting a flame comprises a user placing a finger onto and depressingthe push-button 1030, thereby actuating a gas lever, which in turnactuates an active switch 1015 via contact pressure or electromagneticforce. The actuation of the gas lever also causes a lifting of a nozzle,which allows lighter fluid to be released from the lighter fluid valve.

The second step 1420 of the method 1400 of igniting a flame comprisesthe active switch 1015, activating, via the control unit 1010, thefingerprint sensor 1040 to read or to scan a fingerprint and to indicatevia the LED 1050 to the user that the fingerprint sensor 1040 is in“scan” or “read” mode. In the illustrated embodiment, the fingerprintsensor 1040 of the portable biometric lighter 1000 is located at anupper-facing surface of the push-button 1030, so while the user isdepressing the push-button 1030, the user's thumb would be located onthe fingerprint sensor 1040 enabling the fingerprint sensor 1040 to scanthe user's thumb after the fingerprint sensor 1040 is activated.

The third step 1430 of the method 1400 of igniting the flame comprisesthe control unit 1010 determining whether the scanned fingerprintmatches an authorized user's fingerprint that is stored in the memory1090, and if the control unit 1010 determines that the scannedfingerprint matches an authorized user's fingerprint that is stored inthe memory 1090, the control unit 1010 activates the pulse igniter 1070,e.g., a piezoelectric based circuit, thereby generating a plurality ofhigh voltage sparks via the pole to the nozzle, thereby generating aflame via the lighter fluid flowing through the nozzle.

In some embodiments, when the control unit 1010 determines that thescanned fingerprint matches an authorized user's fingerprint that isstored in the memory 1090, the LED 1050 provides a color indication of amatch (e.g., via a green color that is continuous or blinking). If,however, the control unit 1010 determines that the scanned fingerprintdoes not match an authorized user's fingerprint that is stored inmemory, the LED 1050 will blink in a color (e.g., red) that indicates amismatch or error, a flame is not emitted from the opening 1022 of thelighter 100, and the LED 1050 will revert to illuminating a color (e.g.,blue) indicating the readiness of the fingerprint sensor 1040 to performanother scan of a user's finger.

With reference to FIG. 14, after the user has used the portablebiometric lighter 1000 and wishes to deactivate the lighter 1000, thefourth step 1040 of the method 1000 of igniting a flame comprises theuser removing his or her finger from the push-button 1030. This removalof the user's finger causes the push-button 1030 to move (due to aninternal upward bias, for example, by a spring) from the activatedposition of FIG. 12 toward the deactivated position of FIG. 10, therebyextinguishing the flame and causing the control unit 1010 to deactivatethe fingerprint sensor 1040 to place the fingerprint sensor 1540 in asleep mode.

Referring to FIG. 15, a portable biometric lighter 1500 includes a cover1530, a body 1520, a fingerprint sensor 1540, and an LED 1550.

In the exemplary embodiment illustrated in FIG. 18, the biometric (i.e.,fingerprint) sensor 1540 of the portable biometric lighter 1500 isoperably coupled to a control unit 1510. The biometric sensor 1540 ishoused at least partially within the body 1520 but includes anexterior-facing fingerprint reading surface at a front face of the body1520 that is accessible by a user and that is configured to scan anauthorized user's biometric data (e.g., fingerprint) and any otheruser's biometric data (e.g., fingerprint), which may be stored in thememory 1590 of the portable biometric lighter 1500.

The LED 1550 of the portable biometric lighter 1500 of FIG. 18 isoperably coupled to the control unit 1510 and is configured to provideindications to a user, via blinking and/or solid color or colors, thestatus of the portable biometric lighter functions including but notlimited to setup/teaching mode, low battery, failed scan, and incorrectmatch. For example, in some embodiments, when the portable biometriclighter 1500 is ready to read a user's fingerprint, the LED 1550 isilluminated in a blue color, when the user's scanned fingerprint matchesan authorized user fingerprint stored in the memory 1590, the LED 1550is illuminated in a green color, and when the user's scanned fingerprintdoes not match an authorized user fingerprint stored in the memory 1590,the LED 1550 is illuminated in a red color.

The set switch 1570 of the portable biometric lighter 1500 is operablyconnected to the control unit 1510 and is housed in the body 1520. Inthe embodiment illustrated in FIGS. 15 and 18, the set switch 1570 isaccessible through an aperture 1522 of the body 1520. In someembodiments, the set switch 1570 is configured to activate the controlunit 1510 for accepting a new fingerprint, and to optionally erase aprior fingerprint from the memory device 1590 of the portable biometriclighter 1500 if the control unit 1510 is configured to allow erasing aprior fingerprint and accepting a new fingerprint.

With reference to FIG. 18, a power source 1580 is operably coupled tothe control unit 1510 and is housed within the body 1520. In someembodiments, the power source 1580 is a primary cell battery, arechargeable battery, a photo-voltaic cell, or the like. In theembodiment illustrated in FIG. 18, the power source 1580 provides powerto the control unit 1510 and/or the fingerprint sensor 1540 via thepower lines 1525, but in some approaches, the power source 1580 may beoperatively coupled to the control unit 1510 and/or to the fingerprintsensor 1540 via suitable alternative means.

In the embodiment illustrated in FIGS. 15-18, the active switch 1515 isoperably coupled to the fingerprint sensor 1540 such that upon a userflipping open the cover 1530, the gas lever of the portable biometriclighter 1500 is pulled up and activates the active switch 1515 viacontact force or electromagnetic force. The active switch 1515 uponactivation then activates the fingerprint sensor 1540 to read or scan afingerprint. In some embodiments, upon the user flipping open the cover1530, the gas lever of the portable biometric lighter 1500 is alsoconfigured to lift a nozzle of the portable biometric lighter 1500,which allows the lighter fluid to be released from the lighter fluidvalve.

A pulse igniter 1570, such as a piezoelectric based circuit, isconfigured to produce a high voltage spark from a pole of the portablebiometric lighter 1500 to the nozzle of the portable biometric lighter1500 upon the control unit 1510 determining a match between the scannedbiometric data (e.g., fingerprint) of a user and the biometric data(e.g., fingerprint) of an authorized user, which is stored in the memory1590 of the portable biometric lighter 1500. A flame is subsequentlyproduced when the high voltage sparks come in contact with the lighterfluid that is flowing through the lighter fluid valve to the nozzle.

Referring to FIG. 19, a flowchart illustrates the steps of a method 1900of activating, e.g., igniting a flame, by the portable biometric lighter1500 depicted in FIGS. 15-18. The first step 1910 of the method 1900 ofigniting a flame comprises a user opening a cap 1510, thereby actuatinga gas lever, which in turn actuates an active switch 1515 via contactpressure or electromagnetic force. The actuation of the gas lever alsocauses a lifting of a nozzle, which allows lighter fluid to be releasedfrom the lighter fluid valve.

The second step 1920 of the method 1900 of igniting a flame comprisesthe active switch 1515, activating, via the control unit 1510, thefingerprint sensor 1540 to read or to scan a fingerprint and to indicatevia the LED 1550 to the user that the fingerprint sensor 1540 is in“scan” or “read” mode, which prompts the user to press or swipe his orher finger against the fingerprint sensor 1540. The third step 1930 ofthe method 1900 of igniting the flame comprises the control unit 1510determining whether the scanned fingerprint matches an authorized user'sfingerprint that is stored in the memory 1590, and if the control unit1510 determines that the scanned fingerprint matches an authorizeduser's fingerprint that is stored in the memory 1590, the control unit1510 activates a pulse igniter 1570, e.g., a piezoelectric basedcircuit, thereby generating a plurality of high voltage sparks via thepole to the nozzle, thereby generating a flame via the lighter fluidflowing through the nozzle.

In some embodiments, when the control unit 1510 determines that thescanned fingerprint matches an authorized user's fingerprint that isstored in the memory 1590, the LED 1550 provides a color indication of amatch (e.g., via a green color that is continuous or blinking). If,however, the control unit 1510 determines that the scanned fingerprintdoes not match an authorized user's fingerprint that is stored inmemory, the LED 150 will blink in a color (e.g., red) that indicates amismatch or error, a flame will not be emitted from the opening 1522,and the fingerprint sensor 1540 will subsequently revert to illuminatinga color (e.g., blue) indicating the readiness of the fingerprint sensor1540 to perform another scan of a user's finger. After the user has usedthe portable biometric lighter 1500 and wishes to deactivate the lighter1500, the fourth step 1940 of the method 1900 of igniting a flamecomprises the user closing the cover 1530, thereby extinguishing theflame and causing the control unit 1510 to deactivate the fingerprintsensor 1540 (e.g., place the fingerprint sensor 1540 in sleep mode).
